Chinese Stock Screen Using Weekly 30-Period Moving Average Crossovers

Summary

The document presents a Chinese stock selection rule combining three conditions: daily price amplitude above one percent, no limit-up close on the prior day, and a weekly close crossing above its 30-week moving average. It frames the amplitude and prior-day filter as signs of activity, and the moving-average crossover as a possible upward signal. A holding period is left to the trader. The document includes an indicator-formula reference and a Python example intended to retrieve listings and weekly data. However, the example does not clearly implement every stated condition: its shown loop does not test the prior-day limit-up filter or calculate the amplitude threshold, and the displayed crossover logic should be checked against the intended weekly series. The source itself warns that the approach ignores fundamentals and can produce short-term false signals; it offers no backtest results. It suggests adding other indicators and fundamental measures, then defining entries and exits around risk preferences.

Key ideas

• The screen combines price amplitude, a prior-day limit-up exclusion, and a weekly moving-average crossover.
• The crossover condition compares the close with a 30-week moving average.
• The proposed rationale is to select active stocks with a possible upward trend shift.
• The source warns that technical-only screening can select weak companies and misread short-term moves.
• The supplied Python example does not visibly implement all stated filters, so it requires review before use.
